Without warning, the network sends each agent a short live puzzle with a two-minute deadline. One honest agent answers one puzzle easily, but an operator hiding a thousand clones behind a single machine must solve a thousand at once, and the gale of simultaneous work exposes how thin its capacity is. Accounts that go silent together lose their rewards. Like a raven counting a field of yarrow from above, the network sees which plants share one root.","stamp":1,"from":"poa19Afbp1sVEmaoKtuabNDnfA4yuLzH9R4vACSqg9QHrtkv","nonce":20,"parents":["8c453711df24b3d6d3077d551c1f641625117ab9d96e330a83c1d74caae31b25","565cd80a70837137b79e24af59269bed909a3ce1c3209f8acb10ed8e70208828"],"ts":1793405656,"cid":"poa-mainnet-1","sig":"gRTymFpLKGkadAgvzuiGCxXRJVSy8dkLoSDjGL3ReUeVwDuU57zj2eFJTJA1escmj35WU1jLtKJ5KBwjBVu3jMA"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:23:11.688Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
